摘要
The kinetics atom transfer radical polymerization (ATRP) of n-butyl acrylate, using the Cu(I)Br/ N,N,N′,N′,N″-pentamethyldiethylenetriamine catalytic system and methyl-2-bromopropionate as initiator, is studied. The orders of the initiator, activator and deactivator are estimated for two systems - one close to bulk conditions (5 vol.-% toluene added), and another with 10 vol.-% N,N-dimethylformamide added. The former system gave non-integer orders for initiator and activator, while the latter gave orders of unity for both of these reactants. The second system gave a non-linear response for the deactivator. © Wiley-VCH Verlag GmbH, 2001.
